OEM Carrier Integrated Furnace Control Board HK42FZ016 / 325878-751 for Model PG9MAA060140ADKA

This OEM integrated furnace control board is the factory-specified replacement for the Carrier PG9MAA060140ADKA gas furnace. Originally sold as part number HK42FZ016 and superseded by the updated kit number 325878-751, this board is the central command center of your furnace — sequencing the inducer motor, hot surface igniter, gas valve, and blower in precise timing. When it fails, symptoms typically include a complete no-heat lockout, erratic blower behavior, short-cycling, or a furnace that starts then shuts off within seconds due to a fault code the board can no longer process correctly.

• Specs: 24 VAC thermostat input | Ignitor output: 5A @ 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat blower: 5A, 1/2 HP, 240 VAC | Inducer motor: 4A FLA / 8.0A LRA @ 120 VAC | Operating range: 98–132 VAC @ 60 Hz | Microprocessor-based with LED diagnostic fault codes
• OEM vs Generic: This is a genuine OEM-grade board (ICM Controls, factory-authorized) built to exact Carrier specifications. Generic aftermarket boards often lack factory-calibrated timing sequences, increasing the risk of nuisance lockouts or premature failure of downstream components like the gas valve and igniter.
• Install difficulty: 3/5 — Shut off gas supply and 120V power at the disconnect before beginning. Label or photograph all wire harness connections and terminals before removal. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers, smartphone camera for reference photos. Anti-static precautions required — touch a grounded metal surface before handling the board.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse in original OEM packaging.
